One of my favorite documentaries is on trash on like NBC or one of those type of channels. Trash is different from human waste of course, but it's always an eye opener to know what people have access to, what happens to our waste, etc.

BTW, that smiley poop is an emoticon on the iPhone. I never had a use for it for real until yesterday when my friend's dog swallowed something metal and I suggested she check the poop for it!
